Snapcraft failed with Hash Sum mismatch on Ubuntu 18.04

[MehediH]

Hey,

I am trying to build a snap on Ubuntu and am running into a problem. I tried using electron-installer-snap both as the standalone version, as well as part of Electron Forge. I am running into the exact same issue with the module, possibly conflicting with the module cross-spawn-promise.

Here's the console output:

electron-installer-snap --src=build/TestApp-linux-x64

Snapcraft failed (2)
Re-run with the environment variable DEBUG=electron-installer-snap:snapcraft for details.

I am unaware as to how to address this issue. Please suggest how this problem can be fixed, or if there is a workaround. Thank you!

Per the error message, try rerunning the command with DEBUG=electron-installer-snap:snapcraft to get the output of the snapcraft command that electron-installer-snap runs:

DEBUG=electron-installer-snap:snapcraft electron-installer-snap --src=build/TestApp-linux-x64

This looks like the error to me:

Err http://security.ubuntu.com/ubuntu bionic-security/main DEP-11 64x64 Icons
  Hash Sum mismatch

I don't know why this is happening, but it's more of an apt/Ubuntu problem, so I can't offer any help here. Try checking in Ubuntu's Stack Overflow or forums.

[develar]

@MehediH You can try electron-builder If you don't have custom stage packages, packaging will be done without apt. And if you have custom stage packages, you can always set set _REMOTE_BUILD=true env to build using free remote service (where all system configuration is done properly and proper Ubuntu version is used).

[develar]

Anyway, electron-installer-snap also can be used — but to avoid errors due to your local system, you can use Docker. Image electronuserland/builder is suitable not only for electron-builder, but of course for electron-installer-snap as well. Please note — implied that you build using electron version 2 (because set of packages different since electron 2 uses gtk3).

[malept]

electron-installer-snap automatically uses the correct packages based on whether the app uses Electron >= 2.0 or not.

[MehediH]

Hi guys, I realize this isn't an issue with the module itself but I am still having the same issue. I tried changing the download server for Ubuntu Software but it didn't help, and tried a bunch of other things that didn't help either. Any idea as to what could be causing this?

Also -- I was wondering, would I be able to create a snap package by using Windows Subsystem for Linux?

[develar]

by using Windows Subsystem for Linux?

Snap store validates your app but do not validate how it work across Linux Distros. If you want to be sure, just use docker (to be clear — official snap docker image is not suitable because electron-installer-snap and electron-builder requires node.js/npm) or electron-builder free build cloud service as mentioned above.

[axfelix]

Is there any chance you just need to run an apt-get update because your sources are out of date?

[malept]

It's possible that wiping out the apt cache might work, but I haven't tried it. When I run tests for electron-installer-snap, I use a Docker image of Ubuntu 16.04.

[MehediH]

Cleaning the apt cache doesn't work, neither does changing the sources.

[malept]

Yeah, I would just use a Docker container, such as the one that's used for tests in both electron-installer-snap and Electron Forge. It's Ubuntu 16.04, but that shouldn't matter unless you have some hard dependency that requires a newer Ubuntu version.

[MehediH]

I don't really want to get in the trouble of using Docker. Do you have any Ubuntu env where you can try and repro the problem?

[malept]

The only Ubuntu environments I have are in Docker environments.

That being said, it doesn't seem to be a problem isolated to building Electron apps: https://forum.snapcraft.io/t/ubuntu-18-04-dont-create-a-snap-package-failed-to-update-the-package-cache/5313

Their proposed solution is basically "build the app in a container" (although they use lxc instead of Docker).

[malept]

Evidently it is not currently recommended to build snaps on Ubuntu 18.04 without a container. I tried to run the electron-installer-snap tests with Ubuntu 18.04 and got some interesting errors:

https://travis-ci.org/electron-userland/electron-installer-snap/jobs/405055315#L706-L712

Looking for similar errors led me to https://forum.snapcraft.io/t/python-plugin-glibc-error-in-ubuntu-18-04/5233 which explains why.

[axfelix]

Probably easier to just build on 16.04 then for now?

[malept]

Probably easier to just build on 16.04 then for now?

Either 16.04 or a container running 16.04.

[develar]

That’s why electron-builder uses templates (produced in cooperation with Ubuntu, so, you can be sure that it works and passed Ubuntu Store requirements) instead of snapcraft, otherwise users have a lot of issues, since developer environment is different (each time). It also affects delta updates. That’s why electron-builder offers free public cloud service to build snap even on Linux/MacOS if need (e.g. if you have custom packages).

[MehediH]

I ended up moving to electron-builder and solved this problem with lots of help from @develar. Thanks everyone.
